Stop using `unlikely` in `strict_*` methods #126750

scottmcm · 2024-06-20T16:50:12Z

The strict_* methods don't need (un)likely, because the overflow_panic calls are all #[cold], meaning that LLVM knows any branch to them is unlikely without us needing to say so.

It's unnecessary when that arm leads to a `#[cold]` panic anyway, since controlling branch likihood is what `#[cold]` is all about. (And, well, it's unclear whether `unlikely!` even works these days anyway.)

I don't think the strict_* methods are used enough to make a big difference, but since I ran this on a broader change before,

@tbu- Because deleting unnecessary code is always good -- both for humans and because it does things like shrinks the generated MIR.

(And IIRC they often don't even work right now anyway, so...)

What's the motivation for not using unlikely!?

I had the same thought because of the vague GitHub PR summary, but the summary was updated and the commit message contains the reasoning.
